Hydrogen peroxide (H2O2) is a widely used approach for the sterilization of tissue engineering scaffolds and thermosensitive polymers, as the temperature achieved during sterilization ranges from 37 C to 44 C, and the by-products of the sterilization process are non-toxic. H2O2 is manufactured by the anthraquinone process, which begins with the reduction of anthraquinone to anthrahydroquinone, typically by hydrogenation on a solid palladium catalyst. The net reaction for the hydrogen peroxide reaction process is: H2+ O2-H2O2 H2 and O2 diffuse through a gas film of 80 um thickness to the palladium surface and a reaction occurred with the complete conversion of H2 and O2 to the H2O2 at 1 atm and 15 C After the reaction, the H2O2 diffuses back through the same film into the bulk gas. At the bulk gas, the mole percents of the H2 (A), O2 (B) and H2O2 (C) are 45, 35, and 20 respectively. The binary diffusivities at 1 atm and 25 C are given as DAC (H2-H2O2)-1.7*10 m/s and Dac (O2-H2O2) = 3.9x104 m/s . a) Calculate the DAB at 1 atm and 25 C b) Calculate the effective diffusivity of H2 in the O2-H2O2 mixture . c) Calculate the total molar fluxes of H2, O2 and H2O2
